Write a function to convert the image attached on the top of this page to grayscale.

Sure, here's a Python function that converts an image to grayscale:
```
from PIL import Image
def convert_to_grayscale(image_path):
with Image.open(image_path) as img:
grayscale_img = img.convert('L')
grayscale_img.save('grayscale_' + image_path)
```
You can call this function by passing in the path of the image you want to convert as an argument. The function uses the Pillow library to open the image, convert it to grayscale using the 'L' mode, and save the grayscale image as a new file with the prefix 'grayscale_'.

Message: stale element reference: element is not attached to the page document
This error message typically occurs when a test script tries to interact with an element on a web page that has become stale or no longer exists on the page. There are a few reasons why an element may become stale, including:
1. The page has refreshed or navigated to a different page, causing the element to no longer exist.
2. The element has been removed or replaced by JavaScript code on the page.
3. The element has been interacted with by another script, causing it to become stale.
To resolve this error, you can try the following:
1. Use a wait function to ensure that the element is fully loaded before trying to interact with it.
2. Refresh the page and try again.
3. Locate the element again by using its parent element or a different locator strategy.
4. Use a try-catch block to handle the error gracefully and retry the action if the element becomes stale.
